Why are emission nebulae intrinsically linked to star formation regions?
Answer
They are illuminated by, and composed of the raw material for, newly formed hot, massive stars
Emission nebulae are the visible manifestation of stellar birth; the young, hot stars residing within or adjacent to the gas clouds provide the necessary energy to excite the surrounding material.
